Title: Control of gas burner systems
IPC: F23D14/72
Filed: 1971-04-19
Abstract: 1327309 Gas burner controls AMERICAN STANDARD Inc 19 April 1971 [2 March 1970] 22668/71 Heading F4T [Also in Division G1] A control apparatus for preventing the formation of carbon monoxide in a gas burner BU comprises a total pressure probe PP2 positioned in the flow path of combustion air supplied to the burner and an electric switch DS responsive to the pressure sensed by the probe to control the supply of gas to the burner. The combustion air flow path is defined by a common conduit CC leading from a blower BL to burner BU. Gas is fed from a source SU via a solenoid valve SN, regulator RG and conduit PP1 into the conduit CC at a point downstream of the probe PP2. The probe comprises a curved tube, one end of which faces upstream and measures the combined static and dynamic pressure of the air. The other end of the probe is connected to the switch DS and communicates the total pressure thereto, causing the deflection of a diaphragm DF. If the volume of air supplied by the blower BL is at, or above a predetermined value, the deflection of diaphragm DF, is sufficient to close a contact DK completing a circuit including a power source PS and the solenoid gas valve SN. The valve SN opens and gas flows to the burner BU. If the volume of air drops below the predetermined value, which is about 125% of the volume of air required to form a stoichiometric mixture, the deflection of the diaphragm DF is insufficient to maintain the contact DK closed, thus valve SN closes and the gas supply is cut off. In an alternative embodiment a solenoid valve which is closed when energized is used, the contact DK is placed on the other side of the diaphragm, so that on deflection of the diaphragm the solenoid is de-energized and gas flows to the burner.

Filed: 1959-07-02
Abstract: 894,140. Relative motion detectors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 22, 1960 [July 2, 1959], No. 22807/59. Class 106 (3). Apparatus for detecting relative movement between two members comprises magnetic teeth 3 attached to one member and pick-ups 4, 5 attached to the other, the pick-ups being sensitive to reluctance change caused by the teeth and energizing primary relays RL, RL<SP>1</SP> which energize a secondary relay RL1 which may operate a signal or control. The inductance in a pick-up such as 5 is lowest when it is adjacent a gap 2 between the teeth 3 and then input from the source 8 charges the capacitor 6. If the pick-up remains sufficiently long adjacent a gap, e.g. if the bodies are at a standstill or are moving at less than a predetermined relative speed the capacitor C<SP>1</SP> is fully charged and the coil of relay RL<SP>1</SP> is energized. The relative motion may be rotation. In the embodiment shown in Fig. 2, the pick-up 14 has a winding of high inductance on an E-shaped core and a transformer TR is used. The arrangement is such that the voltage associated with the constant portion of the impedance of the pickup 14 is neutralized by the voltage induced in the secondary winding SW of the transformer TR to ensure that the signal output corresponds to the inductance change due to flux change.

Abstract: 461,278. Sanitary towels. INTERNATIONAL CELLUCOTTON PRODUCTS CO., and NEWMAN, H. Aug. 15, 1935, No. 22989. [Class 81 (ii)] Apparatus for fastening an attachment loop to a sanitary towel comprises means for supporting the towel with a loop positioned around an end thereof and loop-securing means adapted to engage a portion of the loop on one side of said end and draw said portion through the end. As shown, a sanitary towel 10, comprising a pad enclosed in gauze or stockinette 11 extending beyond the pad in the form of end tabs 12, is supported on a table 15 having a raised portion 16 with an upstanding edge serving to position the towel. A pair of hooked needles 18 supported on a cross-beam 19 are raised, to pass through holes 43 in the table and pierce the tabs 12, by a treadle 29 connected, through coil spring cables 26 passing over pulleys 27 and a cross-piece 25<1>, to a rod 24 secured to the cross-beam. The cross-beam is guided by rods 21 and upward movement thereof limited by a stop 32 on rod 24. Flexible loops 13, previously placed around the tabs 12 and comprising, for example, short lengths of tubular stockinette rolled into rings, are moved into engagement with the needle hooks by brushes 38 mounted in pairs on levers 33 and moved downwards and outwards by rods 40. The rods 40 are connected to levers 41 depressed by engagement of the ends 45 thereof with the treadle 29 on further depression thereof against the action of the spring cables 26. The brushes are held against the loops 13 by pawls 48 on levers 46 spring-pressed against the rods 40, the pawls riding over conical collars 45 on the rods and engaging behind them. On release of the treadle 29, the needles 18 descend, by gravity or spring action, and draw the portions of the loops 13 engaged in the hooks through the tabs 12, the remainder of the loops being drawn tightly around the tabs. On reaching its lowest position, the cross-beam 19 engages tail-pieces 50 on the levers 46 and trips the pawls 48 thus permitting the rods 40 to descend under the action of springs 51 and the brushes to return to upper position. The crossbeam 19 is cushioned by a spring 53 from which it rebounds thereby permitting disengagement of the loops 13 from the needle hooks. The Provisional Specification states that the needles may be driven continuously, the loop ends being formed, and the loops being disengaged from the needles and a fresh pad placed in position during alternate reciprocatory cycles.

Title: Improvements in and relating to the separation of phenols from hydrocarbon distillates
IPC: C07C37/76
Filed: 1944-11-20
Abstract: Phenols are separated from distillates containing hydrocarbons and phenols of closely related boiling points by subjecting the distillates to fractional distillation in the presence of steam. The hydrocarbon components are thereby distilled off in the form of their water azeotropes leaving a residue rich in phenols.  The process may be carried out continuously by running the given mixture down a column up which steam is blown.  Alternatively, steam may be blown through the mixture while it is in a still surmounted by a fractionating column.  Instead of blowing in steam, the still may contain a large proportion of water in addition to the given mixture. In all cases the water separated from the condensed azeotropes may be returned to the process. When the given mixture contains paraffinic and aromatic hydrocarbons, fractions boiling within a range of 5 DEG C are treated individually in which case the paraffins will be concentrated in the fractions coming off in the final stages of the steam fractionation.  Coal tar naphtha of boiling range 175 DEG -195 DEG C. and containing 33 per cent. tar acids, 5 per cent. tar bases and 62 per cent hydrocarbons was placed in a still with twice its volume of water and submitted to distillation using a column and dephlegmator.  The residue when separated from water comprised about 20 per cent. of the naphtha and contained 99.7 per cent. tar acids.
